I built a desktop machine quite a while ago … it has an RX560 and has been absolutely troublefree during the last 5-6 years (?) … I forget now when I built it 
It was running TW for a long time, but recently switched to Leap 15.6
Anyway, just an opinion (folks will dispute me), but I will avoid an Nvidia card for any future machine - less problems.
